I'm building a digital clock and so far I've got a 2Hz signal, however my local parts store are closing for a few weeks of renovations and I'm really want to carry on with the clock (I've got everything else I need, I just forgot to get the IC I had in mind to divide by 2).
So I was wondering... is it possible to use an NE555 timer to divide a signal by 2? I've got a couple of these chips spare so if I could use them it would be a great help.
The circuit is a simple one-shot triggered by the input frequency. As long as the one-shot timing is longer than the input one cycle period but shorter than two, the circuit will work.
hey ppl i'm makin a bell which will trigger an alarm if an unknown person enters a room or whatever.it is basically a musical bell that activates with a single puff of breath.Only the members of the family know about the bell so they can puff out and the door will open.
i just needed to know whether ne1 can give me some ideas abt it.Im using ic ne555 and ic um66 too.
